The invention relates to a vehicle body structure for improving the cylindrical collision performance of the side face of a non-bearing type vehicle body, and belongs to the technical field of non-bearing type vehicle bodies. The vehicle body structure comprises the non-bearing type vehicle body, a lower vehicle body of the non-bearing type vehicle body comprises a front floor steel framework and a front floor fixed to the front floor steel framework, the front floor steel framework comprises two threshold beams arranged in the left-right direction in a spaced mode, and a front floor front beam and a front floor middle beam which are sequentially arranged in the front-back direction in a spaced mode and fixedly connected with the threshold beams, and a front seat front installation cross beam which is located in the middle of the front floor front cross beam and the front floor middle cross beam and is fixedly connected with the threshold beams, and two front floor lower longitudinal beams which are located on the inner sides of the two threshold beams and fixedly connected with the front floor front cross beam, the front seat front installation cross beam and the front floor middle cross beam. A reinforcing inclined cross beam which is obliquely arranged is arranged between the front floor middle cross beam and the threshold beams. The side column collision performance is obviously improved, implementation is easy, the manufacturability is good, and the cost is low.
